Install with in-1¶

in-1 gives you a working local Clojure dialect command with a single command and no prerequisites. This installs the dialect (very quickly!) and adds its command directory to PATH. You can then run the command by name.

$ source <(curl -sL in-1.cc) bb && which bb && bb --version
/tmp/in-1/local/bin/bb
babashka v1.13.219

The command is in-1, which uses Makes to auto-install both the dialect and its host language (Java, Go, Python, PHP, etc.) into a local directory. Your system stays clean.

By default, everything lives under $TMPDIR/in-1/ (normally /tmp/in-1/), with the commands in /tmp/in-1/local/bin/. Set PREFIX to choose a different self-contained location:

$ source <(curl -sL in-1.cc) jolt JOLT-VERSION=0.7.1 PREFIX=/tmp/foobar && which jolt && jolt --version
/tmp/foobar/bin/jolt
jolt v0.7.1

This installs the public command as /tmp/foobar/bin/jolt and keeps the versioned Jolt installation and its dependencies under /tmp/foobar/share/jolt/0.7.1/.

You can ask for several dialects at once:

source <(curl -sL in-1.cc) bb clj glj

Note: For the Fish shell, use:
curl -sL in-1.cc | source - bb; and bb

Install the in-1 command¶

Use source <(curl -sL in-1.cc) bb && bb to start Babashka directly, or install in-1 first:

source <(curl -sL in-1.cc) in-1

Then use the shorter commands from Try Dialects or Clojure Tools in the same shell.

Updates and permanent installations¶

Command	Purpose
`source <(curl -sL in-1.cc) -U bb`	Update in-1 and Makes first, then install
`in-1 --local bb`	Keep a dialect for good, under `~/.local`

The second one needs the in-1 command installed; see https://in-1.cc/install/.

Examples¶

Launch a Glojure REPL:

source <(curl -sL in-1.cc) glj && glj

Evaluate a let-go expression:

source <(curl -sL in-1.cc) lg && lg -e '(+ 1 2 3)'

Pin a Babashka version:

source <(curl -sL in-1.cc) bb BABASHKA-VERSION=1.12.218 &&
  bb -e 'babashka.fs/glob'

Or simplify with a shell function:

ccc() {
  local dialect=$1
  shift
  source <(curl -sL in-1.cc) "$dialect" && "$dialect" "$@"
}

ccc clj
ccc bb -e '(+ 1 2 3)'

How it works¶

The sourced script is in-1, which:

Clones itself into /tmp/in-1/ and shallow-clones makeplus/makes into it.
Loads the Makes module for the requested dialect.
Downloads the host language toolchain (Java, Go, Python...).
Downloads and installs the dialect under /tmp/in-1/local/share/<dialect>/<version>/.
Creates a command wrapper in /tmp/in-1/local/bin/ containing the complete runtime environment. Clojure and Leiningen keep their .clojure and .m2 directories inside the installation, and Jolt and Phel start their REPL under rlwrap when it is available.
Adds the wrapper directory to PATH in your current shell.

Everything lives under the selected prefix; remove that directory manually when you no longer need the installation.

See in-1 and makeplus/makes for the implementation details.
